BACKGROUND

A user has an increasing quantity of intelligent devices, and the user often uses a plurality of intelligent devices in one scenario. Scenarios may be usually divided on a per-area basis. For example, being in a living room and being in a bedroom represent two different scenarios, and a user often carries an intelligent device when switching between scenarios. When the user switches between scenarios, the carried intelligent device (such as a mobile phone) may need to be connected to different scenarios, to facilitate the user to execute tasks such as file transfer and collaborative office. During scenario switching, how to implement fast switching of a carried device between different multi-device scenarios is a technical problem that needs to be urgently resolved.

In addition, the internal memory 121 may include a high-speed random-access memory (RAM), or may include a nonvolatile memory, for example, at least one magnetic disk storage device, a flash memory, or a universal flash storage (UFS). The processor 110 runs instructions stored in the internal memory 121 and/or instructions stored in the memory disposed in the processor, to perform various functional applications and data processing of the electronic device 100.

The electronic device 100 may implement an audio function, for example, music playing and recording, through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headset jack 170D, the application processor, and the like.

The button 190 includes a power button, a volume button, and the like. The button 190 may be a mechanical button, or may be a touch button.

The motor 191 may generate a vibration prompt. The motor 191 may be configured to provide an incoming call vibration prompt and a touch vibration feedback. For example, touch operations performed on different applications (for example, photographing and audio playing) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects for touch operations performed on different areas of the display 194. Different application scenarios (for example, a time reminder, information receiving, an alarm clock, and a game) may also correspond to different vibration feedback effects. A touch vibration feedback effect may be further customized.

The indicator 192 may be an indicator light, and may be configured to indicate a charging status and a power change, or may be configured to indicate a message, a missed call, a notification, and the like.

The SIM card interface 195 is configured to connect to a SIM card. The SIM card may be inserted into the SIM card interface 195 or removed from the SIM card interface 195, to implement contact with or separation from the electronic device 100. The electronic device 100 may support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 may support a nano-SIM card, a micro-SIM card, a SIM card, and the like. A plurality of cards may be inserted into a same SIM card interface 195 at the same time. The plurality of cards may be of a same type or different types. The SIM card interface 195 may also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with an external storage card. The electronic device 100 interacts with a network through the SIM card, to implement functions such as conversation and data communication. In some embodiments, the electronic device 100 uses an embedded SIM (eSIM), namely, an eSIM card. The eSIM card may be embedded in the electronic device 100, and cannot be separated from the electronic device 100.

A software system of the electronic device 100 may use a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In this embodiment of the present disclosure, an Android system of a layered architecture is used as an example to illustrate a software structure of the electronic device 100.

FIG. 3 is a block diagram of a software structure of the electronic device 100 according to an embodiment of the present disclosure.

In a layered architecture, software is divided into several layers, and each layer has a clear role and task. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers: an application layer, an application framework layer, an Android runtime and a system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in FIG. 3, the application packages may include applications such as Camera, Gallery, Calendar, Phone, Map, Navigation, WLAN, BT, Music, Videos, and Messaging.

The application framework layer provides an application programming interface (API) and a programming framework for an application at the application layer. The application framework layer includes some predefined functions.

As shown in FIG. 3, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

The window manager is configured to manage a window program. The window manager may obtain a size of a display, determine whether there is a status bar, perform screen locking, take a screenshot, and the like.

The content provider is configured to: store and obtain data, and make the data accessible to an application. The data may include a video, an image, an audio, calls that are made and answered, a browsing history and bookmarks, a phone book, and the like.

The view system includes visual controls such as a control for displaying a text and a control for displaying an image. The view system may be configured to construct an application. A display interface may include one or more views. For example, a display interface including an SMS message notification icon may include a text display view and an image display view.

The phone manager is configured to provide a communication function for the electronic device 100, for example, management of a call status (including answering, declining, or the like).

The resource manager provides various resources such as a localized character string, an icon, an image, a layout file, and a video file for an application.

The notification manager enables an application to display notification information in a status bar, and may be configured to convey a notification message. The displayed notification message may automatically disappear after a short stay without necessarily requiring a user interaction. For example, the notification manager is configured to notify download completion, give a message notification, and the like. The notification manager may alternatively be a notification that appears in a top status bar of a system in a form of a graph or a scroll bar text, for example, a notification of an application that is run on a background, or may be a notification that appears on a screen in a form of a dialog window. For example, text information is displayed in the status bar, a prompt tone is made, the electronic device vibrates, or an indicator light blinks.

The Android runtime includes a kernel library and a virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

The kernel library includes two parts: a function that needs to be invoked by the Java language and a kernel library of Android.

The application layer and the application framework layer are run on the virtual machine. The virtual machine executes java files of the application layer and the application framework layer as binary files. The virtual machine is configured to implement functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

The system library may include a plurality of functional modules, for example, a surface manager, a media library, and a 3D graphics processing library (for example, Open Graphics Library for Embedded Systems (OpenGL ES)).

The surface manager is configured to manage a display subsystem and provide fusion of two-dimensional (2D) and 3D layers for a plurality of applications.

The media library supports playing and recording in a plurality of commonly used audio and video formats, static image files, and the like. The media library may support a plurality of audio and video encoding formats, for example, MPEG-4, Advance Video Coding (H.264), MP3, Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR), Joint Photographic Experts Group (JPG), and Portable Network Graphics (PNG).

The 3D graphics processing library is configured to implement 3D graphics drawing, image rendering, composition, layer processing, and the like.

The kernel layer is a layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

In a non-limiting embodiment, as shown in FIG. 3, the system library may further include a networking manager configured to discover a device in the system 10, where the discovered device may be selected as a prompt device and/or a connection device. In some embodiments, when devices in the system 10 are connected to a same AP to constitute a local area network, the devices in the system 10 are peripheral devices of each other, or all the devices in the system 10 are devices near a user. A networking manager of a device in the system 10 may discover all other online devices connected to the same AP, and all the online devices (including the device and another device in the system 10) connected to the same AP complete networking. In some embodiments, a networking manager of a device in the system 10 finds that an account with which one or some of other online devices in a local area network of a same AP are logged in is an account of the device, or an account with which one or some of other online devices in the local area network of the same AP are logged in is an associated account of the account with which the device is logged in. In this case, other devices that are logged in with the account or the associated account are devices trusted by the device, or all devices that are logged in with the account or the associated account are trusted devices of each other. The devices that are logged in with the account or the associated account and that are connected to the same AP complete networking, to ensure notification security and privacy. In some embodiments, when the devices in the system 10 communicate with each other through a mobile network or the Internet, the networking manager may find, via the mobile network or the Internet, that accounts with which some devices in the system 10 are logged in are a same account or an associated account. In addition, when the devices are located near the user, the devices complete networking, to ensure notification security and privacy. The associated account may be an account authorized by the same account. A distance between devices and a distance between a user and each device may be determined by using BT received signal strength indication (RSSI) ranging or satellite positioning. The networking manager may discover a device near the user in the system 10, and can improve an interaction capability and a collaboration capability between devices, to avoid the user from manually searching for and selecting the device in the system 10, reduce a user operation, and improve efficiency.

FIG. 4 is a diagram of an application scenario according to this disclosure. The application scenario includes the following.

A local device A01 is usually a handheld mobile device of a user, and the user holds the local device and switches between different scenarios. The device is equipped with an operating system. The operating system has a system-level account. A user uses the account to log in to the operating system.

A scenario A02 is a small area in a physical world, for example, a living room or a bedroom at home. A plurality of intelligent devices are configured in the scenario. The intelligent devices are equipped with an operating system, and the operating system has a system-level account. In the scenario, at least one intelligent device is logged in with an account that is the same as a system-level account of a mobile phone.

A user has an increasing quantity of intelligent devices, and the user often uses a plurality of intelligent devices in one scenario. Scenarios may be usually divided on a per-area basis. For example, being in a living room and being in a bedroom represent two different scenarios, and the user often carries an intelligent device when switching between scenarios. When the user switches between scenarios, the carried intelligent device (such as a mobile phone) may need to be connected to different scenarios, to facilitate the user to execute tasks such as file transfer and collaborative office. During scenario switching, how to implement fast switching of a carried device between different multi-device scenarios is a technical problem that needs to be urgently resolved.

To resolve the foregoing problem, FIG. 5 is a schematic flowchart of a device connection method according to an embodiment of this disclosure. As shown in FIG. 5, the device connection method provided in this embodiment of this disclosure includes the following steps.

501: Obtain a location relationship between a first device and each of a plurality of devices in a scenario in which the first device is located.

This embodiment of this disclosure may be applied to the first device.

In a possible implementation, the first device may be located indoors, the scenario in which the first device is located may be a scenario in a physical space or a use scenario, and the physical scenario may be a same room of the first device or a room close to the first device. The use scenario may be a scenario related to a function used by a user when the user uses the first device. For example, when the user uses the first device for office, the scenario in which the first device is located may be a working scenario, and a device in the scenario in which the first device is located may be another device in a same office.

For example, each scenario may correspond to one 3D space. For example, a living room and a study each correspond to one 3D space. Alternatively, a plurality of scenarios may correspond to one 3D space. For example, a plurality of scenarios at home share one 3D space. Usually, based on a distance relationship between locations, a plurality of short-distance scenarios may share one 3D space, and a carried device may perform scenario switching without 3D space switching. Independent 3D spaces may be used between scenarios that are far away from each other. For example, a home and a company are two independent 3D spaces.

Construction of a 3D space: Each terminal may determine information such as a relative location relationship between devices and device types through real-time communication, and then construct a 3D space in real time based on the determined information such as the relative location relationship and the device types. Alternatively, the 3D space may be constructed by a fixed device in a scenario in advance. For example, when a mobile device joins, the fixed device constructs a 3D space model, and then transmits the 3D space model to the mobile terminal. Then, the mobile terminal adjusts the 3D space model in real time based on the model and the newly added device. Optionally, the fixed device is an intelligent device with a fixed location, for example, a television or a lamp.

In a possible implementation, the first device may obtain the location relationship with each of the plurality of devices in the scenario in which the first device is located. For example, the first device may obtain, through calculation, the location relationship with each of the plurality of devices in the scenario in which the first device is located, or the first device may receive the location relationship, sent by another device (for example, a central control device or another terminal device in a system), with each of the plurality of devices in the scenario in which the first device is located, or the first device may calculate a location relationship with a part of the plurality of devices in the scenario in which the first device is located, and receive a location relationship, sent by another device (for example, a central control device or another terminal device in a system), with the other part of the plurality of devices in the scenario in which the device is located.

In a possible implementation, the location relationship may be at least one of a relative distance, a change of a relative distance, a relative direction, and a change of a relative direction.

The following describes how to determine a location relationship between the first device and another device. In an implementation, the location relationship between the first device and the other device may be determined by using the technology such as ultra-wideband (UWB), ultrasound, laser, or vision. For example, the relative distance and the relative direction may be established by using a bidirectional connection between the first device and the other device (the first device and the other device may be required to have hardware that can transmit/receive a wireless positioning signal), and a distance and an angle between the handheld first device and the other device are determined through calculation. In an implementation, triangulation may be performed between the plurality of devices (a handheld device has hardware that can transmit/receive a wireless positioning signal, and there are three or more pieces of fixed hardware that can transmit/receive a wireless positioning signal in a space, where the hardware may exist independently or depends on another device, in the space, on which the hardware has been installed), and absolute positioning of each device may be determined by using a time difference based on a time difference of arrival (TODA). When there is enough hardware that can transmit/receive a wireless positioning signal, a six-degree-of-freedom (6DoF) posture of a device may be determined, and devices may share respective postures, so that a posture of the first device and a posture of the other device may be obtained.

In a possible implementation, when the user uses the first device, there may be a requirement for establishing a connection relationship between the first device and another device in a scenario. After the connection relationship is established, file transfer or data transfer may be performed between the devices (the data transfer may be understood as: transferring, to a connected device, media content presented by a device for presentation. For example, a video or music that is being played may be transferred to another device for continuous playing).

Optionally, to enable the user to conveniently know another specific device with which a connection relationship may be established in a scenario in which the device being used (namely, the first device) is located and a specific location of the other specific device, an interface may be displayed on the first device, and the interface may present another device in the scenario in which the first device is located and a location relationship between the other device and the first device.

Optionally, to enable the user to accurately know a location of another device, the location relationship presented on the interface may be a location relationship between the devices in a 3D space (a 3D location relationship can more accurately represent locations of devices in some scenarios (compared with a two-dimensional location relationship). For example, if horizontal locations of two devices are close to each other, it is difficult for the user to distinguish between the devices based on two-dimensional spatial locations).

Optionally, a location relationship in the 3D space may be represented by using a distance and a direction between two devices, or may be represented by 3D coordinates of the two devices.

In a possible implementation, the first device may display a first device distribution map based on the location relationship, where the first device distribution map includes identifiers corresponding to the devices, and display locations, in the first device distribution map, of the identifiers in the first device distribution map match the location relationship. The user may know, based on the first device distribution map presented by the first device, a location of another device in the 3D space.

In a possible implementation, the first device distribution map may include identifiers of the first device and the other device. Because a location of the first device is a current location of the user, the user may know the location of the other device in the 3D space by using a location relationship between the identifier of the other device and the identifier of the first device.

Optionally, the identifier may be a geometric figure, a skeuomorphic figure, or any other figure having a referential meaning. For example, a mobile phone icon (skeuomorphic figure) may be placed in a sphere (geometric figure) as an identifier of a mobile phone device.

Optionally, a size of the identifier may indicate a distance relationship between the other device and the first device. For example, the size of the identifier is larger for a shorter distance, and the size of the identifier is smaller for a longer distance.

Optionally, the display location and the size of the identifier may indicate a direction relationship between the other device and the first device.

Optionally, the identifier of the first device may be displayed in a central area of the first device distribution map.

In addition, the display locations, in the first device distribution map, of the identifiers in the first device distribution map may match the location relationship at a first angle of view. That is, the locations of the first device and the other device in the 3D space at a specific angle of view may be restored in the first device distribution map. An identifier of a device has specified coordinates in the 3D space, and the coordinates correspond to a physical location of the device corresponding to the identifier. That is, a relative location relationship between identifiers can reflect a relative location relationship between devices in a physical world.

Optionally, when the first device distribution map is presented in the first device, the first device distribution map is presented at a preset angle of view. For example, the identifier representing the first device (namely, the device that is being operated by the user) may be centered and displayed on the interface at an appropriate size.

In a possible implementation, the user may switch a display angle of view in the device distribution map by performing a specific operation on the interface. An angle-of-view switching instruction may be received, and a second device distribution map is displayed, where the second device distribution map includes the identifiers corresponding to the devices, and display locations, in the second device distribution map, of the identifiers in the second device distribution map match the location relationship at a second angle of view.

The second angle of view may be an angle of view obtained by adjusting the first angle of view in a horizontal direction and/or a pitch direction, or the second angle of view may be an angle of view obtained by performing zoom-out or zoom-in on the first angle of view.

For example, the angle-of-view switching instruction may be an instruction corresponding to a swiping operation, and an angle of view in the horizontal direction is adjusted by swiping left or right, to observe an identifier of another device in the horizontal direction. An angle of view in the pitch direction is adjusted by swiping up or down, to observe another visual identifier in a vertical direction.

For example, the angle-of-view switching instruction may be an instruction corresponding to a pinching operation or a spreading operation. The angle of view may be zoomed in by pinching with two fingers, and an identifier of a device is scaled down accordingly. The angle of view may be zoomed out by spreading with two fingers, and an identifier of a terminal is scaled up accordingly. The foregoing angle-of-view switching operation may alternatively be another operation type, and is not limited to the foregoing listed part.

For example, FIGS. 7A and 7B show an operation of swiping left to change the angle of view in the horizontal direction. Through rotation, a sphere a representing a smart sound box is located in the center of a screen, a sphere b, on the right side, representing a television completely disappears from the screen as the angle of view changes, and a sphere c representing another device enters the screen for display. In this way, more devices in a current scenario may be viewed by adjusting the angle of view.

In a possible implementation, the location relationship may represent a relative location relationship between another device and the first device. To enable the user to know an absolute location of the other device in a space, indication information of an environment may further be displayed on a first device distribution interface, for example, may include another object (for example, some objects that are fixedly placed, for example, a table) in the environment.

In a possible implementation, the first device distribution map and the second device distribution map may be referred to as 3D spatial distribution maps. In addition to the 3D spatial distribution maps, the first device may further display a 2D planar distribution map, and the user may switch between the 2D planar distribution map and the 3D spatial distribution map based on a specific operation.

For example, a switching control is configured on a connection interface, to switch between the 2D planar distribution map and the 3D spatial distribution map on the connection interface. For example, the identifier of the first device is displayed in a central area of the 2D planar distribution map, and other devices are displayed around the currently operated device according to a specific rule.

FIGS. 6A and 6B show a diagram of a 3D spatial distribution map corresponding to a physical environment. FIG. 6A is a diagram of the physical environment, and FIG. 6B is the 3D spatial distribution map. A mobile phone, a sound box, and a television communicate with each other to determine respective relative locations of a plurality of devices, so that a location distribution map may be constructed in real time, and identifiers (spheres in FIG. 6A) are added to locations corresponding to the devices, so that the 3D spatial distribution map can be obtained.

When the 3D spatial distribution map is presented in the currently operated device, the 3D spatial distribution map is presented at the preset angle of view. For example, a sphere representing the first device (a device that is being operated by the user, for example, a mobile phone in FIG. 6A) is centered and displayed on the screen in an appropriate size.

Optionally, identifiers corresponding to different types of devices may have different sizes (for example, spheres of different sizes), and a correspondence between a size of a sphere and a device type may be preset. For example, in FIG. 6A, a radius of a sphere of the television is greater than a radius of the sphere of the mobile phone, and the radius of the sphere of the mobile phone is greater than a radius of a sphere of the smart sound box.

Optionally, a size of an identifier further changes with a change of a distance between a device and the first device, to enhance 3D visual effect of a space. For example, when a distance is reduced, a size of an identifier is increased; or when the distance is increased, the size of the identifier is decreased.

In a possible implementation, devices displayed in the first device distribution map may not be all devices in an environment in which the first device is located, but some devices in the environment in which the first device is located, for example, devices (which may also be referred to as collaboration devices in this embodiment of this disclosure) that are logged in with a same account. The first device and the collaboration device have permission to transmit data to each other.

The following describes how to identify the collaboration device from a plurality of devices.

The first device is a device that is being operated by the user, and the first device is logged in with a system-level account. Information about the account may be transmitted to a cloud via a network, or data of the collaboration device may be downloaded from the cloud, to implement cloud synchronization of account data with the collaboration device. The collaboration device is a device that is logged in with the same account as the first device. Information about the account may be transmitted to the cloud via the network, or data of a local device or another collaboration device may be downloaded from the cloud, to implement cloud synchronization of account data with the first device and the other collaboration device. Identities of the first device and the collaboration device are not unique, and may be mutually switched based on an operation of the user.

When the first device carried by the user moves in the scenario, the first device may communicate with all intelligent devices in the current scenario in a manner such as broadcast or Bluetooth communication, to obtain information about the account with which the intelligent device is currently logged in. Then, based on received feedback information, a device that is logged in with the same account as the mobile terminal is identified as the collaboration device.

Certainly, the collaboration device may be alternatively identified in another communication manner. For example, the mobile terminal obtains, from the cloud, identification information (for example, media access control (MAC) addresses) of all intelligent devices that are currently logged in with the same account, and then adds the identification information to a broadcast, so that only specific object (devices that are logged in with the same account) can receive the broadcast and send feedback information to the mobile terminal. Then the mobile terminal identifies the collaboration device based on the feedback information.

A communication means used to identify the collaboration device is not limited in this embodiment of this disclosure.

It may be understood that the foregoing collaboration device may also detect the local device and another collaboration device in a similar communication manner.

It should be understood that, in addition to being used as a device displayed on the first device distribution interface, the identified collaboration device may also be used as a condition of a device with which a connection relationship is subsequently established. In other words, the device with which the first device establishes the connection relationship is selected from the collaboration devices.

502: When a location relationship with a second device in the plurality of devices meets a preset condition, establish a connection relationship with the second device, where the connection relationship is used for file transfer or used to transfer, to a connected device, media content presented by the first device for presentation.

In a possible implementation, the plurality of devices may be collaboration devices.

In a possible implementation, the first device may establish a connection relationship with a device (for example, the second device), in the plurality of devices, whose location relationship with the first device meets the preset condition.

When establishing a connection relationship between a currently used device and another device, the user needs to open a device selection interface. The interface may display another terminal in a scenario in which the terminal is located, and the user may manually select, on the interface, a terminal to which a connection needs to be established. Therefore, each time the scenario in which the terminal is located changes, the user needs to reselect, from an updated interface, a terminal to which a connection needs to be established. The operation is complex, causing poor user experience.

In this embodiment of this disclosure, a terminal may determine, based on a location relationship between the terminal and another device in a scenario in which the terminal is located, a terminal that meets the preset condition, and automatically establish a connection relationship with the terminal that meets the preset condition, so that the user does not need to manually select a terminal each time a scenario changes. This improves user experience.

The following describes a preset condition that a relative location meets.

In this disclosure, the relative location is used as a condition for determining whether to establish a device connection relationship. Whether the relative location meets the preset condition is used as a condition for determining whether to establish the device connection relationship. When the user wants to establish a connection between a currently used device and another device, the user usually approaches the device that the user wants to connect to. Therefore, to make a device connected to the first device meet willingness of the user, the preset condition may be set to: A relative location indicates a device, in a scenario, that the first device is approaching, or a relative location indicates a device, in a plurality of devices in a scenario, that is closest to the first device (or has a maximum approach tendency). Further, a device whose relative location meets the preset condition may be a device that the first device is approaching, or a device in the plurality of devices that is closest to the first device (or has the maximum approach tendency).

For example, an environment in which the first device is located includes a device 1, a device 2, and a device 3. In one case, the first device gradually approaches the device 1 and gradually moves away from the device 2 and the device 3, and a relative location between the first device and the device 1 may indicate that the first device and the device 1 are approaching each other. In this case, it may be considered that the device 1 is a device to which the user most likely wants to connect, because it may be determined that the relative location between the first device and the device 1 meets the preset condition.

In a possible implementation, the location relationship may include a distance, and the preset condition includes that the distance is less than a distance threshold, or the device is a device, in devices in the scenario, having a minimum distance (or a device that needs to meet both conditions of having the minimum distance and having a distance less than the distance threshold). A distance threshold may be related to a device type of a terminal. For example, a distance threshold of a smart sound box is greater than a distance threshold of a smart television.

The distance threshold may also be presented in the 3D spatial distribution map (that is, the first device distribution map and the second device distribution map that are described above). For example, distance thresholds of different devices for establishing connections may be determined based on sizes of identifiers in the 3D spatial distribution map. Different types of devices have different distance determining when establishing connections to the first device.

For example, an identifier is a sphere. Different types of devices correspond to spheres of different sizes, and a gravitational function (similar to a planetary gravitational force) may be defined for the spheres of different sizes. A longer distance indicates a smaller gravitational force. When another device enters a gravitational range of the first device, a gravitational force of a sphere of the device on the first device is calculated. When the gravitational force is greater than a preset value, it is considered that the first device may establish a connection to the device.

The distance may include at least one of a straight-line distance, a horizontal distance, or a vertical distance. A straight-line distance is a length of a connection line between geometric centers or gravity centers of two communication devices. A horizontal distance is a straight-line distance between geometric centers or gravity centers of two devices when the geometric centers or the gravity centers of the two devices are projected to a same horizontal plane. A vertical distance is a straight-line distance between geometric centers or gravity centers of two devices when the geometric centers or the gravity centers of the two devices are projected to a vertical plane.

In a possible implementation, the location relationship may include a change of the distance, and the preset condition includes that the change of the distance gradually decreases, or the device is a device, in the devices in the scenario, with a fastest distance reduction rate.

In a possible implementation, the location relationship may include a direction or a change of the direction, and that the direction or the change of the direction indicate that the device is approaching the first device, or the device is a device, in the plurality of devices in the scenario, that is closest to the first device (or has the maximum proximity tendency) may be used as the preset condition.

In a possible implementation, when the relative location between the first device and the second device in the plurality of devices in the scenario in which the first device is located meets the preset condition, the connection relationship with the second device may be established.

In addition, when the location relationship with the second device in the at least one device meets the preset condition, the second device may be used as a central device, and establishment of a connection relationship between a device, other than the second device, in the plurality of devices and the second device is triggered.

503: After the connection relationship is established, display a first identifier of the first device, a second identifier of the second device, and association information between the first identifier and the second identifier.

To enable the user to conveniently know the device that currently establishes a connection to the first device, after the connection relationship is established, the first identifier of the first device, the second identifier of the second device, and the association information between the first identifier and the second identifier may be displayed, where the association information may indicate that a connection is established between the first device and the second device.

The first identifier and the second identifier displayed in step 503 may be similar to or directly reused as the identifiers in the 3D device distribution map described above. For example, in step 503, the first identifier, the second identifier, and the association information may be displayed at display locations or on interfaces different from those in the 3D device distribution map.

In a possible implementation, the association information may include a change process of changing the first identifier and the second identifier from an unassociated state to an associated state, so that the user can intuitively learn that the connection is established between the second device and the first device and learn of timing of establishing the connection relationship. Optionally, the change process may be displayed by using a special effect of adsorption. For example, a light effect may also be displayed at an adhered portion of the identifiers.

The following describes display styles of the first identifier and the second identifier.

In a possible implementation, the first identifier of the first device and the second identifier of the second device may be displayed on an interface. A display style of the first identifier is related to a device type of the first device; or a display style of the second identifier is related to a device type of the second device.

In other words, different device types may correspond to different display styles, so that the user can conveniently know which device in the scenario is the device. Optionally, the display style may include a display size (for example, a device with a larger size may correspond to a larger identifier), a display shape (for example, may be a polygon such as a sphere or a triangle, or a more skeuomorphic shape), and a display color.

In a possible implementation, the location relationship includes a distance, where the display style of the first identifier is related to the distance; or the display style of the second identifier is related to the distance.

For example, a shorter distance indicates a larger size of the identifier, and a longer distance indicates a smaller size of the identifier.

In a possible implementation, the first identifier, the second identifier, and the associated information may be displayed through one of a status bar, a home screen wallpaper, and a floating window. The following separately describes the display manners with reference to the accompanying drawings.

(1) Floating window:

That is, an example prompt in a form of a bubble and a pop-up window combined with text information is used to inform the user that the connection is established between the first device and the second device. FIGS. 8A and 8B show an example of an interface with information window prompting.

FIG. 8A shows a prompt through a pop-up window. A window, a card, or a bubble is popped up on an interface, and then text information is displayed in the window, the card, or the bubble, to inform the user. Alternatively, a design similar to a dynamic island in FIG. 8B may be used. A card is finally presented through an animation process, and information such as an icon and a text is used in the card to inform the user that the connection is established between the first device and the second device.

(2) Status bar:

That is, an indication icon is added to a location such as a top status bar, a bottom status bar, a drop-down status bar, or a home screen, and the icon indicates that a collaborative connection is established between a current device and another device. FIG. 9 shows an example of adding the indication icon to the top status bar.

(3) Change of a home screen wallpaper:

That is, a change of a wallpaper is used to inform that a connection is established between two devices. Optionally, the 2D planar distribution map or the 3D spatial distribution map described above may be directly used as a home screen wallpaper, that is, the 2D planar distribution map or the 3D spatial distribution map (for example, the first device distribution map or the second device distribution map described in the foregoing embodiment) on the connection interface may be set as the home screen wallpaper in a connection establishment process or after a collaborative connection is established. FIG. 10 is a diagram of an interface in which the 3D spatial distribution map is set as the home screen wallpaper.

When the spatial distribution map is set as the wallpaper, because the wallpaper and the spatial distribution map are a same animation model, interface graphics seen by the user before and after the operation are not changed. The user is informed by using the change of the wallpaper. This can have a notification function and can reduce a sense of intention of a notification manner such as an information window, and this notification manner is natural.

For example, FIG. 10 is a diagram of an effect of setting the 3D spatial distribution map as the wallpaper. In FIG. 10, a collaborative connection is not established between two devices. When a connection is established between two devices, two spheres approach each other and are adhered together after collision, that is, this indicates that the connection is established between the two devices. FIG. 11 shows a home screen wallpaper obtained after a collaborative connection is established. In FIG. 11, after the connection is established, the two spheres are adhered to each other. This indicates that the collaborative connection is established between the two devices, and a multi-device collaboration capability such as data transfer and file transfer may be implemented between the two devices. The 2D or 3D device distribution map can completely present a process of establishing the connection between the two devices. Therefore, when the device distribution map is set as the wallpaper, the user may intuitively "see", from the wallpaper, the process of establishing the collaborative connection between the two devices.

To identify the establishment relationship of the collaborative connection, a corresponding light effect may be displayed at an intersection point of the spheres, for example, a light emitting effect is displayed at the intersection point of the two spheres.

Optionally, after the connection is established, because such adhesion needs to be maintained, coordinates of a device (especially a mobile terminal) in the physical world are no longer in a one-to-one correspondence with a location corresponding to the device in the 3D space. The one-to-one correspondence may be restored after the connection is disconnected.

Optionally, the home screen wallpaper including the first identifier, the second identifier, and the associated information may be displayed for a preset time, for example, only 10 seconds, to implement a notification function. For another example, the home screen wallpaper is displayed until the user performs an operation on an identifier on the home screen or disconnects the connection, and then display of an original wallpaper is restored.

As described in the foregoing embodiment, the second device may be used as the central device, and establishment of the connection relationship between a device, other than the second device, in the plurality of devices and the second device is triggered. In this case, in addition to the association relationship between the identifiers of the first device and the second device, an identifier corresponding to another device in the scenario and an association relationship between the other device and the second device may be further displayed. For example, identifiers of remaining devices may be adsorbed to the identifier of the second device.

After the connection relationship between the first device and the second device is established, data transmission, data transfer, and the like between the first device and the second device may be implemented. The following describes a specific illustration of a data transfer process.

In a possible implementation, the first device may receive a first operation of the user and switch a currently displayed application interface to a connection interface. The connection interface may be an interface corresponding to the home screen wallpaper described above. As described above, the first identifier of the first device, the second identifier of the second device, and the association information between the first identifier and the second identifier may be displayed through the home screen wallpaper. For example, the first operation may be: after the opened application interface is displayed in full screen, performing a gesture of swiping up from the bottom. When the operation is performed, an operating system displays the connection interface in response to the operation.

In a possible implementation, after the first operation is received, in addition to switching the currently displayed application interface to the connection interface, a card corresponding to the application interface may be further displayed on the connection interface in a floating manner. For example, the application interface may be gradually scaled down in a process of performing the first operation, and finally, the application interface is scaled down into a window card and is suspended at the first identifier corresponding to the first device.

In a possible implementation, a second operation may be received, where the second operation indicates to move the card to the second identifier; and media content presented on the application interface is transferred to the second device for presentation. The first operation may be a drag operation on a card. In this embodiment of this disclosure, the card may be dragged to move between different identifiers, to implement application data transfer. For a specific execution process of data transfer, refer to existing data transfer between a plurality of devices, and details are not described herein again.

For example, FIG. 12A to FIG. 12E shows a complete interface change during data transfer. In FIG. 12A, a collaborative connection is established between a mobile phone and another device (for example, a living room television), and spheres representing the two devices are attracted and adhered to each other. This may be directly observed through a wallpaper. When it is expected to transfer music on the mobile phone to the living room television, a music interface (as shown in FIG. 12B) is first displayed, and then a gesture of swiping up from the bottom is performed. As the gesture of swiping up from the bottom is performed, a music application window gradually scaled down, and a part of the wallpaper may be observed (as shown in FIG. 12C). When swiping up to a predetermined location/area (for example, the middle of the screen), the window is scaled down to a form of a window card (FIG. 12D). The window card is dragged to move between different spheres, and the card is released in the sphere corresponding to the living room television, that is, transfer of music data is triggered (as shown in FIG. 12E), and the music data that is being played is transmitted to the living room television through a data channel.

In this manner of displaying the connection interface, when the 3D spatial distribution map is set as the wallpaper, because the wallpaper and the 3D spatial distribution map on the connection interface are the same animation model, the interface graphics seen by the user before and after the preset operation is performed are not changed, so that as perceived by the user, instead of jumping to another interface to perform data transfer, data transfer is directly performed on the home screen. This makes the entire data transfer process smoother and more natural and improves subjective perception experience of the user.

An embodiment of this disclosure provides a device connection method. The method includes: obtaining the location relationship between the first device and each of the plurality of devices in the scenario in which the first device is located; when the location relationship with the second device in the plurality of devices meets the preset condition, establishing the connection relationship with the second device, where the connection relationship is used for file transfer or used to transfer, to a connected device, media content presented by the first device for presentation; and after the connection relationship is established, displaying the first identifier of the first device, the second identifier of the second device, and the association information between the first identifier and the second identifier. In the foregoing manner, a terminal may determine, based on a location relationship between the terminal and another device in a scenario in which the terminal is located, a terminal that meets a preset condition, and automatically establish a connection relationship with the terminal that meets the preset condition, so that a user does not need to manually select a terminal each time a scenario changes, and the user does not need to determine a specific device that needs to be connected; and provided that the user approaches a device that needs to be connected in the physical world, a connection to the device can be automatically established. This improves user experience.

In addition, when the user switches from one scenario to another close scenario, the terminal device may disconnect a connection to a device in the original scenario, and automatically establish a connection to a terminal, in the new scenario, that meets a condition.

For example, for two scenarios: a living room and a study, the terminal device is in the living room initially, and after the user carries the terminal device into the study, the terminal device disconnects a connection to a device in the living room and is automatically connected to a device (a device that meets the preset condition) in a space range of the study.

In a possible implementation, the location relationship includes at least one of a distance, a change of a distance, a relative direction, and a change of a relative direction.

In a possible implementation, the location relationship includes a distance, the preset condition includes that the distance is less than a distance threshold, and at least two different types of devices correspond to different distance thresholds.

In a possible implementation, the location relationship is a location relationship in a 3D space, and the processing module 1302 is further configured to: display a first device distribution map based on the location relationship, where the first device distribution map includes identifiers corresponding to the devices, and display locations, in the first device distribution map, of the identifiers in the first device distribution map match the location relationship at a first angle of view; and receive an angle-of-view switching instruction, and display a second device distribution map, where the second device distribution map includes the identifiers corresponding to the devices, and display locations, in the second device distribution map, of the identifiers in the second device distribution map match the location relationship at a second angle of view.

In a possible implementation, the processing module 1302 is further configured to: when the location relationship with the second device in the at least one device meets the preset condition, trigger establishment of a connection relationship between a device, other than the second device, in the plurality of devices and the second device.

In a possible implementation, the processing module 1302 is further configured to: receive a first operation, switch a currently displayed application interface to a connection interface, and display, on the connection interface, the first identifier of the first device, the second identifier of the second device, and the association information between the first identifier and the second identifier.

The processing module 1302 is further configured to: display, on the connection interface in a floating manner, a card corresponding to the application interface; receive a second operation, where the second operation indicates to move the card to the second identifier; and transfer, to the second device for presentation, media content presented on the application interface.
